Maps is not something you use to make anything better, they are used because there is no other way to make it work. There are a lot of other considerations, you may want multiple figures on the scene, you may want to animate..on so on.

If you have seen a V4 animation with Marvelous Designer you know the feeling of true joy. All the years you never have seen anything like it, not even from Disney! What a kick! But then you hear your poor brand new nuclear powered 16GB computer with GTX 680 straining with the effort almost to give up and you understand what you are up against.

So there are a lot of factors to take into consideration and as usual, art is long life is short. To advocate a stance that go against a lot of people who are more successful than you in fact 99% of the professionals isn't very smart, if I may say so.
